Discovered in 1962 in Namibia and named for the man who discovered it, this variety of chalcedony (which is a member of the quartz family) with its swirling colors, is a pseudomorph of quartz with embedded fibers of amphibole minerals in varying degrees of alteration. These fibers cause a chatoyancy similar to that seen in tigereye.
